The location is as good as it gets. I think something between Nana and Asok near the main street is best for Bangkok. This is a 2 minute walk to Nana BTS.
The hosts are experienced professionals. They'll adjust to your maintenance level, whether you want to be left alone or need more assistance. They let me switch the couch.
Noise level is good. Despite being near the main street, it's located on an alley that's not busy. The 2 bedroom/ 2 bathroom unit (307), the upstairs neighbors drag chairs often which can be a little annoying but the ceiling insulates the sound pretty well. In the 2 bedroom/ 1 bathroom unit (304), the upstairs neighbor is very respectful and barely ever makes friction with the ground.
The place is functioning well. The internet barely ever disconnects and can stream 1080p+. Airco works good, the beds are firm for good sleep and the bedrooms can get very dark.
There is no gym, but there is a newish one five minutes away (Fitness 24 Seven) which allows you to prepay w/o card and doesn't scam like you some of the other gyms in Bangkok.
